MBR
Biological treatment plus membrane separation. Considered where high-quality treated water, reuse or a compact footprint matter.
Sewage Treatment Plants
Sewage treatment plants engineered for reliable treatment & reuse
MBR, MBBR and SBR sewage treatment — from the first site discussion to long-term plant performance for industrial and commercial facilities.
What an STP does
Treat sewage so it can be discharged or reused
Hitech Fluid System designs and implements sewage treatment plants for industries, housing and commercial facilities based on actual sewage characteristics, capacity, available space, treated-water requirements and operating conditions.
After water is used in toilets, washrooms, kitchens and canteens, organics, solids and other constituents are added. An STP combines physical and biological processes — and often a tertiary stage — so treated water can be discharged or reused. Selecting an STP should not begin with technology alone.
Not every STP should be designed the same way
Two facilities generating the same quantity of sewage may still need different treatment approaches. We treat STP work as an engineering requirement, not a standard equipment package.
- Daily sewage generation and peak loads
- Inlet wastewater characteristics
- Required treated-water quality
- Whether treated water will be reused
- Available installation area
- Power and operating requirements
- Existing collection infrastructure
- Maintenance capability and future expansion
Technologies
MBR, MBBR and SBR — plus the stages around them
MBBR
Carrier media provide surface area for biological growth in a continuous process. Practical for many industrial and commercial applications.
SBR
Biological treatment through controlled fill, react, settle and withdraw cycles. Useful where batch operation fits the load pattern.
Typical sewage-treatment stages
- Primary treatment — screening and settling of coarse solids
- Secondary treatment — biological reduction of organics
- Tertiary treatment — polishing for reuse or tighter discharge
- Extended aeration / activated sludge where appropriate
- Sludge handling and disposal planning
- Odour control and operational access
MBR vs MBBR vs SBR
Don’t choose the technology first. Understand the water. Understand the requirement. Then choose the process.
| Consideration | MBR | MBBR | SBR |
|---|---|---|---|
| Core approach | Biological treatment + membrane separation | Biological treatment using carrier media | Biological treatment in controlled cycles |
| Treatment mode | Continuous with membrane separation | Continuous biological treatment | Sequenced batch treatment |
| Membrane | Yes | Not required for biological stage | Not required for biological stage |
| Reuse suitability | Strong option where correctly designed | Possible with suitable tertiary treatment | Possible with suitable tertiary treatment |
Treated sewage is a resource — not always a waste
Where technically appropriate, treated sewage can be reused for landscaping, toilet flushing, cooling-related applications, utility water and selected industrial uses. The process should be designed around where the water ultimately needs to go.
Our STP engineering process
- Understand the site, sewage generation and objective
- Assess wastewater through laboratory partners where required
- Define capacity, quality, reuse and space
- Select MBR, MBBR, SBR or a combined train
- Engineer, install, test and commission
- Support through AMC, O&M, troubleshooting or revamping
Existing STP not performing?
An underperforming STP does not automatically mean the entire system must be replaced. Hitech Fluid Systems can assess plants originally installed by other vendors — odour, foaming, load, breakdowns, operating cost, biological performance and reuse quality.
- Treated-water quality is not as expected
- Unpleasant odour or excessive foaming
- Plant cannot manage present load
- Frequent equipment breakdown
- Facility capacity has increased
- Treated water now needs to be reused
Featured project
50 KLD MBR Treatment System — Panasonic Appliances India, Chennai. Membrane-based sewage treatment delivered inside a major manufacturing environment. Industrial customers are not simply buying tanks, pumps and membranes — they need a system that works with the facility and can be supported after commissioning.
Frequently asked questions
What is an STP?
An STP treats sewage generated from toilets, washrooms, kitchens and canteens before appropriate reuse or discharge.
What STP technologies does Hitech Fluid Systems provide?
Hitech Fluid Systems works with MBR, MBBR and SBR, and can also discuss conventional biological processes such as extended aeration where they fit the site.
Which is better: MBR, MBBR or SBR?
There is no single best technology. Selection follows sewage characteristics, capacity, space, treated-water quality, reuse and how the plant will be operated.
Can STP-treated water be reused?
Yes, depending on treatment quality and the intended application. Typical non-potable uses include landscaping, flushing, utilities and selected industrial purposes.
Can Hitech Fluid Systems repair an STP installed by another company?
Yes. We first identify the process, equipment or operational problem, then recommend the appropriate correction or upgrade.
Why does my STP smell?
Odour can come from biological conditions, aeration, loading, stagnant zones, sludge management or operating practices. A site assessment is better than assuming a single cause.
Discuss your sewage treatment requirement
Whether you need a new STP, want to improve reuse, or have a plant that is underperforming, start by sharing the site conditions.
