Product Details:

An Oil and Grease Trap with Oil Skimmer is a wastewater treatment device designed to intercept, separate, and remove fats, oils, greases (FOG), and floating oils from water streams before they enter the sewer or treatment system. This combined system protects drainage, sewage treatment plants, and the environment from blockages and pollution caused by such contaminants.

How It Works

• The Oil and Grease Trap operates on the principle of gravity separation. Wastewater containing oils, greases, and solids flows into the trap where the flow rate is controlled to allow separation. Since oils and greases are lighter than water, they float to the surface, forming a distinct layer, while heavier solids settle at the bottom. The clearer water flows out under an outlet baffle.

• The Oil Skimmer is a mechanical device integrated or installed downstream to continuously remove the floating oil layer. It uses belts or discs made of oleophilic materials that attract and lift the oil from the surface. The collected oil is scraped off and discharged into a collection container for proper disposal or recycling.

Components

• Inlet and Outlet Pipes: Control the flow into and out of the trap.

• Baffles: Slow the water flow and aid in separation of oil/grease from water.

• Oil Retention Chamber: Where oils and greases accumulate.

• Oil Skimmer Assembly: Belt or disc skimmer device to remove floating oils.

• Sludge Zone: Solids settle at the bottom for periodic removal.

Benefits

• Prevents clogging and blockages in sewer systems by intercepting FOG.

• Reduces environmental pollution and foul odors.

• Facilitates efficient recovery and disposal or recycling of oils.

• Low maintenance with automated skimming reducing manual cleaning frequency.

• Suitable for commercial kitchens, food processing units, automotive workshops, and industrial effluent treatment applications.

This Oil and Grease Trap with Oil Skimmer is an essential solution for efficient wastewater pre-treatment, protecting infrastructure while recovering valuable oils from wastewater

Pressure Sand Filters (PSF) are widely used in wastewater and water treatment processes to remove suspended solids, turbidity, and particulate impurities through a multilayer filtration media, typically consisting of graded sand, gravel, and sometimes other materials like anthracite.

Working Principle:

• Water is forced under pressure through the filter bed composed of layers of sands and gravel with varying particle sizes.

• Suspended particles and impurities are trapped within the sand bed as water percolates downward.

• The filtered water is collected through a bottom drainage system and passed to subsequent treatment stages.

• Over time, the filter media accumulates trapped solids, causing increased pressure drop.

• A backwash process reverses water flow, agitating the media bed to dislodge and wash away trapped solids, restoring filter efficiency.

Key Components:

• Filter Vessel: A pressure-resistant cylindrical tank housing the filtration media. Commonly made from MS, FRP, or stainless steel.

• Filter Media: Graded silica sand, gravel layers with different particle sizes arranged to optimize filtration.

• Distribution System: Perforated pipes or nozzles to ensure even feed water distribution and prevent channeling.

Product Details:

A Waste Water Filtration System is a critical component of wastewater treatment, designed to remove suspended solids, impurities, chemicals, and other contaminants from wastewater to improve water quality for discharge or reuse.

Key Components of Waste Water Filtration Systems:

• Mechanical Filtration:
  Includes screens, sand filters, bag filters, and cartridge filters to remove suspended solids, debris, and large particles. Sand filters involve passing water through a bed of sand or gravel, trapping particles physically.

• Absorption Filtration:
  Activated Carbon Filters (ACF) are widely used for adsorption of organic compounds, chlorine, odors, and some heavy metals. They improve the taste, color, and safety of water.

• Ion Exchange Filters:

• Membrane Filtration:
  Advanced membranes such as ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO) remove bacteria, viruses, dissolved solids, and heavy metals, providing near-pure treatment levels. Reverse osmosis uses semi-permeable membranes under pressure to filter out microscopic contaminants.

• Self-Cleaning and Automatic Filters:
  For continuous high flow applications, self-cleaning filters use automatic backwash to maintain flow and filter efficiency.

Types of Filtration Systems Used:

1. Sand Filters: Effective for large particle removal; commonly used as a pre-treatment.

2. Bag and Cartridge Filters: Remove medium to fine suspended particles.

3. Activated Carbon Filters: Remove organic molecules, chlorine, odors.
