Sewage Treatment Plant
Sewage is a resource that can be recycled for various uses like gardening, toilet flushing, car wash, cooling towers. Faced with the alarming fact that over 60% of the sewage generated in our country goes untreated, with its negative impact on human health, the government is focusing on waste management through centralized sewage treatment plants and by mandating large upcoming real estate projects to have their own treatment facility.The objectives of biological treatment, some useful definitions, the role of microorganisms in the biological treatment of waste water, and biological processes used for waste water treatment are introduced in this section to provide a perspective for the material to be presented in this section. The removal of dissolved particulate carbonaceous BOD and the stabilization of organic matter found in wastewater are accomplished biologically using a variety of microorganisms, principally bacteria. Micro organisms are used to oxidize the dissolved and particulate carbonaceous organic matter into simple end products and additional biomass.
The principal biological processes used for waste water treatment can be divided into two main categories: suspended growth and attached growth processes. The types of microorganisms involved the specific reaction that they perform, the environmental factors that affect their performance, their nutritional needs, and their reaction kinetics. These subjects are considered in the design section and Meco Technologies Pvt. Ltd. focus these areas for the overall performance of the plant. Meco Technologies Pvt. Ltd. has the technical capability and expertise for the successful design and operation of all these processes to our valuable customer.
Membrane Bio-Reactor Systems (MBR)
The term ‘membrane bioreactor’ (MBR) is usually used to define wastewater treatment processes where a perm-selective membrane e.g. microfiltration or ultrafiltration is joined with a biological process – a postponed growth bioreactor.
Membrane Bioreactor (MBR) systems proposal some effective and economic compensations equated to conventional wastewater treatment plants. By incorporating GE’s membrane technology, MBR systems eliminate the need for secondary clarifiers and tertiary treatment. This allows for increased performance with a smaller footprint.
MBRs differ from ‘polishing’ methods where the membrane is employed as a discrete tertiary treatment step with no return of the active biomass to the biological process.
Moving Bed Biofilm Reactor (MBBR)
With the Moving bed Bioreactor (MBBR) an carefully solution is offered for wastewater treatment if the “bulk” of the pollution load must be disposed of (as means of cost reduction) or if applicable discharge regulations are not as strict.
With this request we offer progressive wastewater treatment solutions for the industrial and municipal markets. These solutions significantly increase the capacity and efficiency of existing wastewater treatment plants, while minimizing the size of new plant deployments.
This method makes it possible to attain good efficiency results of disposal with low energy consumption. This process is used for the removal of organic substances, nitrification.
Filter Press
An industrial filter press is a tool used in separation processes, specifically to separate solids and liquids. The process uses the principle of pressure drive, as provided by a slurry pump. Among other uses, filter presses are utilized in marble factories in order to separate water from mud in order to reuse the water during the marble cutting process.
Generally, the slurry that will be separated is injected into the center of the press and each chamber of the press is filled.
- Optimal filling time will ensure the last chamber of the press is loaded before the mud in the first chamber begins to cake. As the chambers fill, pressure inside the system will increase due to the formation of thick sludge
- Then, the liquid is strained through filter cloths by force using compressed air or water. Pressurized water requires more time to pass through the chambers compared to pressurized air, but the use of water is more cost efficient.
Bar Screen
A bar screen is a powered filter used to remove large objects, such as rags and plastics, from wastewater. It is part of the primary filtration flow and naturally is the first, or preliminary, level of filtration, being installed at the influent to a wastewater treatment plant. They typically consist of a series of vertical steel bars spaced between 1 and 3 inches apart.
Bar screens come in many designs. Some employ automatic cleaning mechanisms using electric motors and chains, some must be cleaned manually by means of a weighty rake. Items removed from the influent are called screenings and are collected in dumpsters and disposed of in landfills. As a bar screen collects objects, the water level will rise, and so they must be cleared regularly to prevent overflow.
