Biological wastewater treatment

Aquatreat's anti-fouling aspirators have been developed in response to the growing challenges posed by flushed wipes and rugs, and other heavy debris conditions in water and wastewater treatment systems. Operating without aerosols or any need for fine screening, the anti-fouling aspirators can be integrated into either new or existing treatment

Puriflo has wide experience with activated sludge treatment systems for treating industrial effluent. The treatment consists of an aeration tank in which a bacterial culture is given oxygen by aeration, enabling it to consume the organic content of the effluent or sewage. After treatment in the aeration tank, the flow passes to a settlement tank

Smart Storm offers a carefully-selected range of bacterial products for effluent bioaugmentation, based on specific formulations of naturally-occurring microbes, enzymes and plant extracts. Biological treatments that use micro-organisms and nutrients to stimulate contaminant biodegradation are increasingly important in wastewater management

MBBR25 and MBBR18 are modular automated biological treatment systems for municipal and industrial wastewater, designed to meet strict AMP8 discharge standards. Each unit uses three aerobic chambers with 40% fill HDPU carrier media at 840m²/m³ surface area, dual perforated diffusers, and integrated automation for efficient BOD5, ammoniacal

The media used in trickling filters needs a high surface area but must have a sufficiently open structure not to restrict the natural draft air flow. Traditional filters used blast furnace slag but modern plastic media like Biofil and Bioball provide a much higher surface area per unit volume of media with a low air side pressure drop. This makes

Puriflo has wide experience in building sequential batch reactors, a form of activated sludge treatment in which both aeration and settling take place in the same tank. The process can only be applied in cases where the flow to the plant is suitable or where it is possible to discharge a large volume in a short time. It is possible, by the

Puriflo's membrane bioreactors feature submerged aerated media, offering high performance with low electrical running costs and minimal maintenance. They are manufactured with flat-sheet membranes and are designed specifically for each application. Services include installation and commissioning

The AnoxKaldnes™ Hybas™ hybrid process combines AnoxKaldnes™ MBBR biofilm technology and an activated sludge process in the same tank. The Hybas™ hybrid process is suitable for nitrogen removal from municipal wastewater and for some industrial applications. High nitrification is achieved with a reduced suspended sludge age

Complete modular aeration systems are available for immediate hire including: drop in, submerged

The Volcano III floating lake aerator provides extremely high flow rates resulting in huge volumes of water turnover and high DO or dissolved oxygen levels. Volcano III is suitable where a minimal surface display is required but efficient aeration is of importance. It has high LPM pumping rates and oxygen transfer capabilities. Options to add

The digestate treatment system, designed by Colloide, is built around the ultra-efficient Selective Vaporisation system. Colloide's system is compact with a small footprint, and highly innovative with low energy and low chemical consumption. Separated liquor or unseparated liquor and solids can be treated to selectively remove ammonia and only a

MSE Hiller is a UK leader in the supply, installation and rental of centrifuges and sludge dewatering equipment. The company undertakes bespoke biological treatment solutions. Working in partnership with leading industry names in industry, it is committed to minimising cost and environmental impact, as well as maximising efficiency for customers

Puriflo specialises in the design of submerged aerated media plant for treating waste water in food processing industries. Submerged aerated media plant can deal with much higher loadings per cubic metre of tank volume than an activated sludge plant. No daily checks are required on the mixed liquor solids volume. Submerged aerated media plant uses

The OxiAir Shallow lake aerator uses a silent compressor that pumps air up to the surface through diffuser membranes situated on the lake bed. This allows air to travel up to the lake surface, entraining water, breaking through the thermocline layer and reducing the risks of thermal stratification. Each diffuser circulates an approximate volume of 11,605 litres of water per minute

Aquatreat's 9” fine bubble disc diffuser provides efficient oxygen transfer for municipal, industrial and leachate treatment plant. The unit is mechanically strong and can be operated over a wide range of airflows with minimum maintenance. It is compatible with all air distribution pipelines
