SBR Wastewater

The sequencing batch reactor (SBR) is a fill-and-draw activated sludge system for wastewater treatment. In this system, wastewater is added to a single “batch” reactor, treated to remove undesirable components, and then discharged. Equalisation, aeration, and clarification can all be achieved using a single batch reactor. To optimise the performance of the system, two or more batch reactors are used in a predetermined sequence of operations. SBR systems have been successfully used to treat both municipal and industrial wastewater. They are uniquely suited for wastewater treatment applications characterised by low or intermittent flow conditions specifically:

  • Mining Camps
  • Breweries
  • Wineries and Restaurants
  • Caravan and Camping Parks

With SBR WWTPs you have more control of the changing volumes and effluent produced.

Micro Filtration

Silicon carbide ceramic membrane is made from pure SiC powders by recrystallization technology at an extremely high sintering temperature of 2400℃, then formed the porous and asymmetric membrane structure, according to the membrane pore size difference, mainly proposed for liquid filtration applications by membrane separation technology as microfiltration and ultrafiltration. It is a kind of inorganic membrane with separation function, which is coated of SiC ceramic material as the filtration medium.

The SIC ceramic membrane is also a kind of semiconductor, the surface has negative charge in a wide PH range, the isoelectric point is near PH3, which belongs to impurity conductivity, the membrane can be used for long time in harsh environment of strong acid and alkali (PH value 0-14), good stability for most sewage, especially oil-water permeability (oil-free). Almost no etching with any solvent at 1500 ℃.

Electro Membrane Filtration

  • Electrodialysis is a membrane process that uses alternating Anion–selective membranes (AMs) and Cation-selective membranes (CMs), placed between an Anode (+) and a Cathode (-). Due to the applied electric field, anions will move towards the Anode and cations will move towards the Cathode. Anions are stopped by the CMs and the cations by the AMs, creating a process flow with low ion concentration (Dilutant) and a process flow with high ion concentration (Concentrate). A pair of a CM and a AM and both areas between these membranes is a Cell Pair. A Cell Pair is the basis unit of a stack, and is repeated “(n)” times. 

The number of cell pairs in an actual stack varies depending on the electrodialysis system, with as many as 600 cell pairs in a typical industry-scale system. In electrodialysis suspended solids which carry positive or negative electrical charges can increase the resistance of the membrane dramatically, are deposited on the membrane surface. However, in electrodialysis the problem has been eliminated to a large extent by reversing in certain time intervals the polarity of the applied electrical potential which results in a removal of charged particles that have been precipitated on the membranes. This technique is referred to as electrodialysis reversal (EDR).

Reverse Osmosis

Reverse osmosis is a water purification process that uses a semi-permeable membrane (synthetic lining) to filter out unwanted molecules and large particles such as contaminants and sediments like chlorine, salt, and dirt from drinking water. In addition to removing contaminants and sediments, reverse osmosis can also remove microorganisms and bacteria. It gets water clean down to a molecular level, leaving only pure water behind.

In reverse osmosis, an applied pressure is used to overcome the osmotic pressure and push the water from high concentration of contaminants to low concentration of contaminants. This means it’s being forced in reverse and the contaminated water is trying to move into the pure water, but because it must pass through a filter first, the contaminants get trapped and only the pure water passes through; resulting in the cleanest possible drinking water – which is exactly what we want!
