Sewage Treatment Plants by Kiran Techno Services Private Limited

Introduction

Sewage Treatment Plants are installed and commissioned at various industries for treating waste before discharging them into water bodies. The plant receives the waste from domestic, commercial and industrial sources and removes the harmful materials from the sewage that damage water quality.

The prime objective of a sewage treatment plant is to make the industrial effluents free from elements that are harmful for human and environment.

We offer following equipments:

Clarifier

Clariflocculators

Effluent Treatment Systems

Water Pollution Control Systems

Waste Treatment Plants

Working Principle

Preliminary Treatment: Removal of coarse solids and other large materials found in raw wastewater

Primary Treatment: Removal of settle-able organic and inorganic solids by sedimentation, and the removal of float-able materials by skimming

Secondary Treatment: Removal of residual organics and suspended solids

Application

All these sewage treatment plants are used for treating sewage and effluents coming out from commercial establishments, residential areas and industries.

Clarifier

Product Description

Clarification is the process to remove suspended solids from water. It is the economical and an essential part of effluent treatment plants and other raw water treatment plants. Depending upon the plant, the clarifiers are available in wide varieties of shapes. In large scale wastewater treatment facilities, large circular open-air clarifiers are preferred.

Types of clarifiers:

Solids Contact Clarifiers

Secondary Clarifiers

Primary Clarifiers

Working

The clarifiers operate on the principle of gravity-separation. The separate solids would flow downward and settle on tapered floor.

The untreated oil is forced towards the periphery of the bowl by centrifugal forces

Then the oil is passed up through the disc stack

Actual separation takes place here in the channel formed between two discs

The two forces act on each solid or liquid particle

The particles are pushed upwards with the oil stream towards the centre while the centrifugal force directs it to the periphery

The residual force on denser particles will drive them towards the periphery

While the less dense particles (oil) will be directed towards the centre of the bowl and raise to the outlet connection

Technical specifications

Rotational speeds: 7,000 to 9,000 rpm

Number of discs: up to 150

Separation distance between Discs: 0.5-0.6 mm

Application areas:

All these clarifiers are widely used in almost all types of water treatment plants.
