Advance Water Treatment Technologies

Integrated Water & Wastewater Treatment Systems

Mechasol Water Technologies provides engineering-led, integrated systems for water intake, transfer, and treatment across municipal, industrial, and infrastructure applications. Solutions are designed around hydraulic loading, influent characteristics, site conditions, and operational philosophy, and can be delivered as equipment packages or turnkey EPC scopes.

In modern water projects, reliability is driven by the “chain” performance: headworks protection, stable flow control, solids handling, separation, mixing/aeration, sludge volume reduction, and packaged treatment units. Mechasol’s approach is to deliver these as coordinated process blocks—with consistent material selection, maintainability, and automation readiness across the plant.

Target sectors include aquaculture, flood control, irrigation networks, aqueduct systems, and industrial applications, supported by both stationary and floating pumping systems and a full set of treatment plant mechanical equipment.

1) PRE-TREATMENT EQUIPMENT

Headworks Protection & Solids/Grit Handling

Pre-treatment reduces downstream loading and protects pumps, mixers, and separation stages. Mechasol emphasizes that pre-treatment selection depends on wastewater characteristics, hydraulic calculations, and topographic constraints, which is the correct engineering basis for headworks design.

1.1 Mechanical & Screening Systems

Mechasol’s screening scope covers both coarse and fine screening solutions, including:

  • Front-Raked Chain Screen

  • Rear-Raked Chain Screen

  • Flex Screen

  • Cable Mechanical Screen

  • Linear Mechanical Screen

  • Traveling Grab Screen

  • Basket Screen

  • Manual Screen

  • Perforated Screen

  • Step Screen

  • Belt Screen

  • Spiral Screen

  • Channel Drum Screen

  • Rotary Belt Screen

  • Externally-Fed Drum Screen

  • Internally-Fed Drum Screen

Key engineering parameters typically applied for screen selection and sizing:

  • Design flow (average / peak / storm) and channel approach velocity

  • Required opening (bar spacing / perforation) and expected screenings load

  • Headloss allowance (clean and blinded) and bypass philosophy

  • Cleaning method (mechanical vs manual), wash/compaction, and odor control integration

  • Material selection (CS vs SS) based on corrosion, H₂S exposure, and cleaning chemicals

1.2 Screenings Dewatering & Handling

Screened waste can retain significant water. Mechasol supplies:

  • Screen (Waste) Press (with dewatering capacity noted up to 70% in catalogue)

  • Spiral Conveyor Press

  • Conveyors (multiple types and capacities) for transfer to containers or disposal points

1.3 Grit & Grease Removal

Grit/grease removal prevents abrasion, sediment accumulation, and operational instability in downstream processes. Mechasol provides:

  • Linear Type Grit & Grease Scraper

  • Compact Unit

  • Grit Separator

  • Grit Cyclone

  • Oil Separator

  • Waste Container

  • Belt / Spiral Conveyors (for grit and screenings logistics)

Catalogue positioning aligns with standard headworks design practice: remove grit/oil early to reduce plant load and improve overall stability.

2) FLOW CONTROL EQUIPMENT

Level Control, Isolation, Emergency Tightness

Flow control equipment forms the “hydraulic backbone” of treatment facilities, used for water level control, flow direction, isolation, and maintenance bypass. Water tightness becomes critical for emergency conditions and planned maintenance—explicitly emphasized in the catalogue.

2.1 Penstocks & Isolation Devices

  • Wall Penstock

  • Channel Penstock

  • Weir Penstock

  • Stoplog

  • Telescopic Valve

Typical decision factors:

  • Sealing type (EPDM/NBR), bidirectional sealing needs, and allowable leakage class

  • Actuation (manual, electric, pneumatic, hydraulic) and emergency operation

  • Civil interface (embedded frames, wall/channel mounting, anchor design)

  • Corrosion class and coating/SS requirements by water chemistry

3) SCRAPERS

Settled & Floated Solids Removal Across Treatment Stages

Scrapers remove settled sludge and/or floated materials and are used in multiple stages of treatment, delivered in carbon steel or stainless steel per spec.

3.1 Scraper Types (Catalogue Scope)

  • Circular Driven Sediment Scraper

  • Central Driven Sludge Scraper

  • Chain Surface Scraper

  • Chain Surface and Bottom Scraper

Engineering notes

  • Clarifier diameter/geometry, sludge blanket behavior, and solids loading dictate torque and drive sizing

  • Material selection and wear strategy (UHMWPE wear strips, SS chain options) improve lifecycle cost

  • Skimming and sludge withdrawal arrangement defines scum handling efficiency

4) MIXERS

Rapid, Slow, Static & In-Pipe Flocculation

Mixers ensure homogeneous mixing, prevent sedimentation, and improve process efficiency. Mechasol states availability in slow speed, fast speed, and submersible types, and includes the following product families:

4.1 Mixer Types

  • Rapid Mixer

  • Slow Mixer

  • Pipe Flocculator

  • Static Mixer

  • Dynamic Mixer

Key selection parameters commonly used:

  • Tank volume, required G-value, and retention time

  • Chemical dosing points and mixing intensity zones (flash mix vs flocculation)

  • Mounting configuration (top-entry, side-entry, submersible)

  • VFD requirement and redundancy philosophy

5) AERATORS

Mass Transfer for Odor, Gas Stripping & Oxidation

Mechasol describes aerators as operating on gas-liquid equilibrium principles and being used to remove dissolved gases and address taste/odor problems, as well as oxidation applications.

5.1 Aeration & Flotation Types (Catalogue Scope)

  • Vertical Shaft Aerator

  • Horizontal Shaft Aerator

  • Jet Aerator

  • Dissolved Air Flotation (DAF)

Engineering notes

  • Oxygen transfer efficiency (OTE), alpha/beta factors, and diffuser/fine bubble vs mechanical selection

  • DAF: recycle ratio, saturation pressure, bubble size distribution, and polymer strategy

  • Odor-related applications often integrate with upstream screening/grit zones and odor treatment systems

6) SLUDGE DEWATERING

Volume Reduction & Disposal Cost Optimization

Mechasol lists sludge dewatering equipment as essential to reduce sludge volume and space requirements and supplies the following scope:

6.1 Dewatering Equipment (Catalogue Scope)

  • Belt Press

  • Filter Press

  • Pre-Dewatering Belt

  • Polyelectrolyte Preparation Unit

  • Lime – Alum – FeCl₃ Preparation Unit

Engineering notes

  • Polymer system design (maturation time, dilution water quality, skid redundancy) is often decisive in real performance

  • Filter press is typically preferred for higher DS and lower disposal cost; belt press for continuous operation and simpler mechanics

  • Chemical prep systems enable conditioning strategies (alkalinity/pH and coagulation support) to stabilize dewatering performance

7) PACKAGE TREATMENT UNITS

Compact, Fast Deployment Treatment Systems

Mechasol describes biological package units as compact designs integrating piping, pumps, and aeration, with quick installation requiring only power + inlet/outlet connections—ideal for fast commissioning.

7.1 Package Unit Types (Catalogue Scope)

  • Steel Type Biological Treatment Unit

  • Concrete Type Biological Treatment Unit

  • Continuous System Biological Treatment Unit

  • Chemical Treatment Unit

8) ODOR TREATMENT SYSTEMS

Odor Control & Gas Treatment for Water Facilities

Odor control is a critical requirement in wastewater treatment plants, pumping stations, sludge handling areas, and headworks where H₂S, NH₃, mercaptans, and VOCs are generated. Uncontrolled odor emissions lead to environmental complaints, corrosion, and safety risks.

Mechasol designs integrated odor treatment systems based on emission characteristics, air flow rate, and removal efficiency targets.
