2. About Us
• Maverik Inc. is multifaceted company involved in the business
of water treatment and waste water treatment projects. Its
activities include Engineering, Designing, manufacturing,
marketing and servicing. We execute the projects (water
treatment waste water treatment and effluent recycling) on
turnkey basis.

3. About Waste Water
Sewage treatment or domestic waste water treatment is the
process of removing contaminants from the waste water. It
includes physical, chemical & biological processes to remove all
the contaminants. The objective is to reclaim water & solid
sludge back in to mainstream of environment. Sewage is created
by residencies, institutions, hospitals, commercial & industrial
establishments.
Sewage treatment generally involves three stages
primary, secondary and tertiary treatment

4. Waste Water Treatment
Primary treatment consists of temporarily holding the sewage in
an inert basin where heavy solids can settle to the bottom while
oil, grease and lighter solids float to the surface. The settled and
floating materials are removed and the remaining liquid may be
discharged or subjected to secondary treatment. Some sewage
treatment plants that are connected to a combined sewer
system have a bypass arrangement after the primary treatment
unit. This means that during very heavy rainfall events, the
secondary and tertiary treatment systems can be bypassed to
protect them from hydraulic overloading, and the mixture of
sewage and storm water only receives primary treatment.

5. Waste Water Treatment
• Secondary treatment removes dissolved and suspended
biological matter. Secondary treatment is typically performed
by indigenous, water-borne micro-organisms in a managed
habitat.
• Secondary treatment may require a separation process to
remove the micro-organisms from the treated water prior to
discharge or tertiary treatment

6. Waste Water Treatment
Tertiary treatment is sometimes defined as anything more than
primary and secondary treatment in order to allow rejection into
a highly sensitive or fragile ecosystem (estuaries, low-flow rivers,
coral reefs, etc.). Treated water is sometimes disinfected
chemically or physically (for example, by lagoons and
microfiltration) prior to discharge into a stream, river, bay, lagoon
or wetland, or it can be used for the irrigation of a golf course,
green way or park. If it is sufficiently clean, it can also be used for
groundwater recharge or agricultural purposes

11. Modified UASB Technology - Our Forte’
• The digester is specially designed to process different types of substrates; be it
liquid, semi solid or solid, it works on the basic principles of UASB technology
• The digester is compatible with numerous raw materials viz. animal dung, poultry
manure, food, vegetable & fruit waste, slaughterhouse waste, starch, dairy &
distillery waste water, sugar mill press mud, sisal unit effluent, De Oiled Cake,
molasses, human waste, Sewage Waste Water, etc. To name a few
• The main difference between a regular UASB reactor and the MUASB digester is
the acceptance of biodegradable solid contents along with liquids in the range of
0.1% to as high as 10%. The digester can be constructed in a variety of ways with
a floating dome or with fixed dome with separate balloon storage. It is capable of
taking multiple feed stocks with high SRT. Because of high SRT, the most of the
influent solids are digested within the reactor and converted into biogas. And the
yield of Biogas is higher than any other technologies

13. Why Anaerobic Technology?
• High efficiency for the removal of organic matter as well as for
the nutrients.
• High treatment efficiency for biodegradable sludge
• Reduction of greenhouse gas emissions through methane
recovery
• Minimal energy requirements
• Relatively short detention time (due to the relatively small
volume of the tanks)
• Biogas production (it is additional benefit)

14. Benefits of Our Technology
Benefits of Anaerobic Treatment
• Low production of stabilized sludge
• Very low nutrient requirements
• Little if any energy requirement
• Production of biogas
• Reduction of green house gas emissions
• Very high loading rates (up to 35 kg COD.m-3.day -1)
• Relatively simple in operation and maintenance
