Aerobic digestion for isolated commercial wastewater treatment plants

by Jet Inc.     based in Cleveland, OHIO (USA)

Jet’s package commercial wastewater treatment plants (aerobic treatment systems) have made it possible for motels, shopping centers and service stations to be constructed along interstate highways far from any town. With a Jet package commercial wastewater treatment plant: Subdivisions can be developed miles beyond sewer lines; factories can be erected in rural areas; and people can live and work in isolated areas in places such as Guam and Peru as well as in the world’s deserts, deep valleys and mountain ranges.

Air control for wastewater treatment aeration

by Kurz Instruments, Inc.     based in Monterey, CALIFORNIA (USA)

Aeration Process Introduction: Waste Water Treatment removes impurities and contaminants from a com¬munity`s sewage utilizing a number of different processes and a variety of equipment. One of the processes is the use of surface aerated basins that use aerobic micro-organisms to remove 80 to 90% of organic matter in waste water. Oxygen concentration in the water basins is a critical factor to promote the optimum micro-organism growth rate needed to treat the water in the shortest amount of time. As a result, large compressors are used to force air through hundreds of air diffusion filters at the bottom of the aeration basins, providing a constant 24/7 supply of oxygen to the micro-organisms in the water.

Wastewater Treatment for the Chemical industry

by HydroThane STP BV     based in KC `s Hertogenbosch, NETHERLANDS

In addition to the food industry, biological anaerobic and aerobic technologies can be applied in the chemical and pharmaceutical industry as well.

Typical for the chemical and pharmaceutical waste water is the high organic pollution, which is often limited to only a few components that can be present in high concentration. Every production site has its own unique effluent composition.

This type of effluents require tailor-made solutions. The Upflow Anaerobic Sludge Blanket (UASB) process and the External Circulation Sludge Bed (ECSB) process from HydroThane are worldwide proven processes for the treatment of this type waste water.

Some chemical /pharmaceutical production processes where anaerobic technology has been applied are:
- Purified Terephthalic Acid (PTA)
- Phenol
- DMT
- Penicillin
- Insulin.

Wind or solar powered sewage treatment plants

by Water Technology Engineering Ltd. (WTE)     based in Bolton, UNITED KINGDOM

Use natural air currents for aerobic sewage treatment via venting pipes. Alternatively, they can be solar powered using a very low energy 12 Volt fan. The FILTERPOD requires no electricity for the treatment process. They finally allow modern, high quality sewage treatment for all regions of the world, even for off-grid locations.

Wastewater solutions for municipal sewer control

by Real Tech Inc.     based in Whitby, ONTARIO (CANADA)

Problem: A significant portion of the operational costs of a conventional municipal wastewater treatment plant employing an aerobic biological treatment unit comes from electricity costs associated with aeration. In many cases, the aeration rates are kept at the maximum level to ensure that the plant’s effluent is in compliance with the regulations. The critical parameter for regulatory purposes and treatment efficiency, BOD, takes 5 days to measure through standard methods providing almost no value to the plant operators in terms of adjusting aeration rates and chemical dosing.

Anaerobic Digester for Biogas Plant

by Center Enamel Co,.Ltd     based in Guangzhou, CHINA

Glass fused to steel tank is made by a special process, called vitreous enamel coating ,which is an advanced technology for anti-corrosion purpose of steel plate. Tanks are coated both inside and outside with enamel .Today, glass fused to steel tank is widely used in wastewater treatment projects as aerobic and anaerobic reactors of UASB,EGSB,SBR,BAF,USR,CSTR, and equalization tank, clarifier, and sludge holding tank. It has proven its superior resistance to thermal and chemical when facing water with extremes in pH and temperature.
