Biological wastewater 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

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

Colloide manufacture and install submerged membrane bioreactors. The MBRs are the most technically advanced products in their field, giving unparalleled performance in wastewater treatment. Colloide's submerged membrane bioreactor can be installed as part of a new-build plant and integrated to upgrade existing plants, giving an excellent quality

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

Membrane Bio Reactors (MBR) from MSE Systems combine activated sludge treatment with a membrane liquid-solid separation process. The system uses low pressure Micro Filtration (MF) or Ultra-Filtration (UF) membranes, eliminating the need for clarification and tertiary filtration. MBRs are suitable for municipal and industrial wastewater treatment

Colloide design and install Sequential Batch Reactors. With flexible plants, and various aeration options they are capable of completing the treatment process in one tank. Despite the compact bulk free design Coilloide's SBRs are capable of treating high incoming loads with no recirculation pumps and minor energetic consumption. Customised

Integrated fixed film activated sludge (IFAS) process combines biofilm technology and the conventional activated sludge (AS) treatment. IFAS technology is compact, cost effective and retains high biomass concentration in the reactor. This process uses suspended a suspended buoyant media, usually made of polypropylene (PP) or high density

A wide range of municipal or industrial effluents are treated by fixed film or suspended media biological processes. Aquatreat engineers can assist with existing process plant or advise on the most effective options for new facilities or extensions. Services include: sampling; testing; pilot testing of plant; provision of temporary or permanent plant

Biostyr™ biofilters combine a biological reactor and a physical filter in a single structure for the removal of organic, nitrogenous and particulate pollution in the treatment of municipal and industrial wastewater. Biostyr™ biofilters are available in several configurations for carbon removal, nitrification, nitrification / denitrification, and post-denitrification, and have a modular structure

Submerged Aerated Filters consists of a series of cells containing buoyant media retained by a screen with air distribution fed from a blower. Because there is no limitation on air flow through the media, it is possible to use media with higher surface area per unit volume than in trickling filters. Bioball and Biomarble media have proved highly

The Siltbuster range of Moving Bed Biofilm Reactors (MBBR) is designed to provide packaged plug and play aerobic biological treatment, easy to operate and easy to maintain. Based on established fixed film biological treatment, the MBBR uses media with a specific area of up to 800m2/m3, providing a substantial greater treatment capacity – up to

Warden Biomedia filter products (like Biopebble, Bioball 220, Biomarble 310 and Bioflow 800) are high-surface-area plastic media designed to host bacteria for water treatment. The media is designed to be a permanent, non-clogging alternative to traditional materials like gravel or slag, with improved removal of pollutants

Colloide solutions for effluent treatment are determined by site-specific factors including: existing plant size / capacity / condition; raw water quality; required final quality of treated effluent; space available; etc. Activated sludge treatment uses microorganisms cultivated in the treatment process to break down organic matter into carbon
