Biological sewage treatment

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

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

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

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

Biodigester / BAF is a wastewater treatment system designed to process organic waste water. Uses biological processes to break down waste, reducing environmental impact: on-site organic wastewater treatment system; reduces environmental impact by treating waste before discharge; compact size suits restricted installation areas; low odour and quiet

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

The AnoxKaldnes™ MBBR (moving bed biofilm reactor) is a biological wastewater treatment where an active biofilm grows on small specially-designed plastic carriers that are kept suspended in the reactor. The AnoxKaldnes™ MBBR technology allows a flexible reactor design, and can be used to upgrade existing plants and biological processes

Phragmifiltre® is a reedbed technology that provides complete treatment of macerated or raw sewage in a single wetland system, with no pre-settlement and little or no power requirement. The system can treat raw non-settled sewage from 20 to 5,000 PE achieving removal efficiencies of 92% COD, 97% BOD5, and 97% suspended solids

In moving bed biofilm reactors the buoyant media is free to move within an aerated reaction chamber. The MBBR integrated fixed film activated sludge (IFAS) is essentially an activated sludge suspended growth process but with the biomass fixed to the media. It can perform all the same process variations such as nitrification, denitrification and

As domestic sewage and industrial effluent treatment plants, Ovivo’s Rotating Biological Contactors (RBCs) remove soluble, biodegradable, organic materials from domestic and industrial wastewater, achieving a high quality final effluent that is safe for discharge. Driven by low power motors, the RBC technology is one of the most efficient systems
