Mapal Green Energy, developers of the innovative floating fine bubble aeration system (FFBA) for wastewater treatment, has appointed Strand Hanson in preparation for an AIM float in early summer this year. The brokers are Beaufort Securities.

Mapal Group, as the post float company will be known, has a rapidly developing reputation across a number of industry sectors, with over 40 sites live worldwide. In the UK, interest to date has been centered around the water utilities, where the company has successfully sold in projects to Thames Water, United Utilities and Anglian Water. The company has also reported interest from the pulp and paper, agriculture, food and beverages and petro chemicals sectors, all of which generate wastewater requiring a biological aeration treatment process.

In its regulation of the UK water industry, the implementation of the latest Ofwat Asset Management Plan (AMP6) in April of this year has perhaps presented the company with it biggest opportunity to date. Ofwat now requires water utilities to focus on the total operating cost of plant, which now  includes maintenance and energy usage, not just the initial capital cost, as was previously the case.

The Mapal technology is well placed to address this new regulatory hurdle. Floating fine bubble aeration approaches the challenge of waste water biological aeration by marrying the strengths of surface aeration technology – easy to install and accessible for maintenance - with the efficiency which is derived from sub surface fine bubble aeration systems. With no moving parts generating friction and driving high energy consumption, a key benefit for users of Mapal’s system is its dramatically reduced energy and maintenance bills.

Earlier this year, the company was shortlisted for the 2015 Environment and Energy Awards.

Mapal Green Energy pioneered the concept of floating fine bubble aeration (FFBA)as a more efficient means of treating waste water for both utility companies and industry applications.

Tests around the world have shown that in some cases, compared to surface aeration, a plant’s energy consumption can be reduced by up to 70% using the Mapal system,.

With over 40 installations worldwide, Mapal's floating fine bubble aeration technology has been proved to meet and exceed stringent effluent quality parameters including the reduction of : BOD5, TSS, COD, Tkn and Ammonia.

In the UK, the system is being used by Anglian Water, Thames Water and United Utilities.

Mapal’s innovative equipment floats on the surface, so wet and live installation is the norm, which makes for a very fast changeover of plant and a minimal downtime. The units are made from robust stainless steel, so have a long life and as a modular system, the installation can be added to or reduced quickly and easily. Thus far, their largest UK installation is designed to handle a flow rate of up to 10,450m3/day in wet weather.

The Mapal technology can be adapted for aggressive and hazardous liquids and is therefore suitable for application across a wide range of industry sectors where a solution based on aeration is required. Liquid waste from the paper, food and beverages, petro chemicals, agriculture  and other industries can all be treated. 

The origin of the EU’s best-available-technique (BAT) guidelines for pulp and paper installations go back over 10 years, but it is only recently that they have surfaced again for most mill operators, who now need to urgently consider emissions controls to improve anti-pollution measures.

The guidelines form a reference for regulators to set permit conditions under the Industrial Emissions Directive and all regulated industries, including the pulp and paper sector, are expected to achieve compliance with BAT and their Associated Emission Levels (AEL) rules within strict timeframes. Permits for all installations will require updating by early 2018.

In particular, the BAT guidelines will have much tighter limits on pollutant levels and will cover by way of example, wastewater that is discharged into rivers. Current EU pulp production mostly uses the kraft process, and under the guidelines, the acceptable level of pollutants for the chemical oxygen demand of waste water per tonne of dry pulp has been halved. As such, the industry will need a mixture of end-of-pipe measures, better technology and improved management, if it is to meet the new rules.

The pulp and paper sector is a significant energy user and currently ranks fourth in the industrial sector for its energy use, according to the Industrial Efficiency Technology Database, consuming by some estimates up to 6% of global industrial energy use. Filtering and the removal of contaminants from the wastewater is known to be very energy demanding, with mechanical surface aeration and sub-surface jet aeration systems for biological treatment demanding high volumes of electricity. Consequently, the search is on for energy efficient wastewater treatment technologies which can now deliver against the specific challenges of pulp and paper manufacturing.

One such technology company which is well placed to deliver against this need is  Mapal Green Energy, with its innovative Floating  Fine Bubble Aeration technology (FFBA), currently used by Anglian Water, Thames Water and United Utilities in the UK. The same technology has also been deployed successfully in South Africa in the pulp and paper sector and again in factory farming installations in Israel, where the challenges of treating aggressive and hazardous liquids echo many of the issues faced in the pulp and paper industry.

A revolutionary solution, floating fine bubble aeration approaches the challenge of wastewater oxygenation by marrying the strengths of mechanical surface aeration technology – easy to install and accessible for maintenance - with the efficiency which is derived from sub surface fine bubble aeration systems. With no moving parts generating friction and driving high energy consumption, a key benefit for users of Mapal Green Energy’s floating fine bubble aeration system is its dramatically reduced energy bill. Tests around the world have shown that in some cases, compared to mechanical surface aeration, a plant’s energy consumption can be reduced by significant amounts. In the UK, Anglian Water reported a 22% drop in energy consumption using Mapal’s system, as compared to its previous mechanical aeration technology.

Mapal GE CEO Zeev Fisher comments, “We have a well proven technology in use at over 40 sites around the world, including in the pulp and paper sector and by leading Utility companies in the UK, where  regulatory pressure has long been a feature of the industry. The technology is perfectly suited to the new challenges laid down in the latest EU BAT-AEL rules and our in house teams can advise on all aspects of systems design and installation.”

Are bubbles the answer to treating wastewater in the pulp and paper industry?

Pulp and paper making is renowned as one of the most water intensive industrial production processes anywhere. Processing pulp requires huge quantities of water to deliver a consistent structure. The constituents of paper are processed into a sludge form and with water used at almost every stage of production, the result is the generation of a high quantity of highly contaminated level of wastewater which has to be treated to meet regulatory and environmental consents.

Some estimates suggest up to 17.4 cubic metres of water are required to produce one metric tonne of paper, with the raw wastewaters from pulp and paper and board mills often requiring complex biological treatment processes. It’s a challenge the industry has embraced however, with around 92% of the water used returned to the environment, after it has been treated. The filtering and removal of contaminants from the wastewater can be very energy demanding, with mechanical surface aeration and sub-surface jet aeration systems for biological treatment, known to consume high volumes of electricity. Energy reduction, operational cost reduction and water recycling initiatives are therefore important objectives for many paper manufacturers.

In pulp and paper mills, waste water treatment can take on several forms, from filtering through to biological treatment process.  For biological treatment to be effective, the waste water needs to be effectively aerated,

Many UK mills will use mechanical surface aeration techniques in order to supply the required oxygen for bacteria to achieve an aerobic biological treatment, especially where an activated sludge process is involved. However, mechanical surface aerators are typically expensive to operate and maintain, old, prone to breakdown, due to the number of moving parts andhave considerable energy consumption, all of which adds up to relatively high operating costs.

Enter Mapal Green Energy with its innovative Floating  Fine Bubble Aeration technology (FFBA), currently used by Anglian Water with further deals signed with  Thames Water and United Utilities for systems to go live before the end of the year, where Mapal GE’s equipment will be used to treat domestic and industrial wastewater in a range of lagoons and reactors. The same technology has also been deployed successfully in South Africa in the pulp and paper sector and again in factory farming installations in Israel, where the challenges of treating aggressive and hazardous liquids echo many of the issues faced in the pulp and paper industry.

A revolutionary solution, floating fine bubble aeration approaches the challenge of wastewater oxygenation by marrying the strengths of mechanical surface aeration technology – easy to install and accessible for maintenance - with the efficiency which is derived from sub surface fine bubble aeration systems. With no moving parts generating friction and driving high energy consumption, a key benefit for users of Mapal Green Energy’s floating fine bubble aeration system is its dramatically reduced energy bill. Tests around the world have shown that in some cases, compared to mechanical surface aeration, a plant’s energy consumption can be reduced by up to 70% using the Mapal system, with savings of 50% regularly achieved.

Commenting on the ease of installation of the system, Mapal’s UK sales manager Andy Carling said, “By substituting a surface mounted propeller for a system of blowers and fine bubble diffusers, not only is energy consumption reduced, but installation and maintenance is dramatically simplified. The system does not require a tank to be drained, nor does it need to be attached to a concrete floor. Aerators are automatically adjustable to water depth and because they float, are always level, thus delivering an even flow of oxygen within the reactor.”

Mapal’s units are made from robust stainless steel, so have a long life and as a modular system, the installation can be added to or taken away from quickly and easily.

A technology which is creating waves amongst the UK’s water utilities looks set to revolutionise wastewater treatment in selected sectors of the pulp and paper industry too.
