Wastewater Industry
The Wastewater Treatment Industry requires continuous process measurement systems and control. At Tek-Trol, we offer unique solutions tailored to these requirements. Our products are safe and easy to operate and maintain, ensuring sustained savings and productivity.
WASTEWATER SOURCES, INTAKE AND MECHANICAL TREATMENT
Domestic household, industrial, and agricultural practices are the main sources of wastewater. The primary objective of wastewater treatment is to remove coarse solids and other large particles from raw water. In the Grit Channel process, the velocity of incoming wastewater is controlled, in order to allow sand, grit, and stones to settle to the bottom of the channel while keeping the majority of the suspended organic material in the water column.

BIOLOGICAL TREATMENT
The secondary treatment process consists of biological treatment. It includes aerobic processes and anaerobic processes. The main purpose of this process is to reduce and remove the concentration of organic and inorganic compounds. Up to 90% of organic matter can be removed through this process. The biological treatment utilizes microorganisms such as bacteria and protozoa to decompose organic matter. Post this treatment, a water pump is used as a secondary clarifier.

EFFLUENT LINE
Milk powder is the process of removing water content by boiling the milk under vacuum conditions or at low pressure and temperature. The resulting concentrated milk is then sprayed into a fine mist of hot air to remove further moisture and get transformed into powder.

SLUDGE COLLECTION AND CONCENTRATION
The sludge produced by primary and secondary treatments contains 99% water. The thickening tank allows the sludge to collect, settle and separate from the water for up to 24 hours. Then, the water is sent back to the aeration tanks for further treatment.

DIGESTER AND METHANE STORAGE
Post thickening, the sludge is treated to make it safer for the environment. The sludge is placed in an oxygen-free tank called the digester and heated up to 90ºF – 95ºF for a period of 15 – 20 days. This stimulates the growth of anaerobic bacteria, which consume the organic material in the sludge. The digestion process stabilizes the thickened sludge by converting much of the material into water, carbon dioxide, and methane gas. The black sludge that remains after digestion has the consistency of pea soup and has little odor.

SLUDGE DEWATERING AND DISPOSAL
Dewatering reduces the liquid volume of sludge. Digested sludge is sent through large centrifuges that operate like the spin cycle of a washing machine. The force from the extremely fast spinning of the centrifuges separates most of the water from the solids in the sludge, creating a substance known as biosolids. Adding a substance called organic polymer improves the consistency of the “cake”, resulting in a firmer, more manageable product.
