Classification of Solids in Wastewater

In wastewater treatment, the solid content is classified based on the size and nature of the particles present. The classification helps in determining the appropriate treatment processes for removing or separating solids from the wastewater. Here are the common classifications of solid content in wastewater:

Different Types of Asphalt Binders - Bitumen Grades

In road construction and asphalting the streets, bitumen is mainly used as a binder in the road layers. In road construction, penetration grade bitumen and viscosity grade bitumen are the most commonly used grades; however, other types of bitumen can also be used. According to the "different types of bitumen used for road construction" article by Infinity Galaxy, there are various grades of bitumen applied in road construction.

Types of Solid Waste Collection Systems

For the successful waste minimization programs, the waste must be collected appropriately and be transported to the recycling and recovery facilities or disposal areas. There must be efficient waste collection methods and good programs for waste collection because they affect the success of waste management programs significantly.

Types of Solid Wastes - Based on Origin and Composition

Solid wastes are the organic and inorganic waste materials such as product packaging, grass clippings, furniture, clothing, bottles, kitchen refuse, paper, appliances, paint cans, batteries, etc., produced in a society, which do not generally carry any value to the first user(s). Solid wastes, thus, encompass both a heterogeneous mass of wastes from the urban

Types of GeoTextiles

Woven geotextiles have interlacing filaments or yarns in two perpendicular directions - the longitudinal (or warp) direction and the crosswise (or weft) direction. Woven geotextiles often have greater tensile strength in the warp direction than the weft. Whereas non-woven fabrics are formed by linking filaments using:

Gradation Of Aggregates | Types of Aggregate Grading

Types of Grading7•Dense-or well-graded aggregate–Has gradiationclose to the FWHA maximum density grading curve.•Gap-graded aggregate–Has only a small percentage of particles in the mid-size range.•Uniformly graded aggregate–Composed mostly of particles of the same size.•Open-graded aggregate–Contains only a small percentage of small-size particles.

AASHTO Soil Classification System - AASHTO Chart

The AASHTO Soil Classification System classifies soils into seven primary groups, named A-1 through A-7, based on their relative expected quality for road embankments, sub-grades, sub-bases, and bases. Some of the groups are in turn divided into subgroups, such as A-1-a and A-1-b. Furthermore, a Group Index may be calculated to quantify

Headrace Tunnels - Definition, Uses and Types of Headrace Tunnels

There are different definitions for headrace tunnel (HRT) used at different scenarios. “Headrace tunnel takes water from connecting channels and convey it to the fore bay or directly to the penstock provided with surge shaft” depending upon the project and site requirements some times also known as power tunnels.

Types of Activated Sludge Process - Plug Flow, Complete Mix, SBR

In CMAS, mixing of tank contents is sufficient so that ideally concentrations of mixed-liquor constituents, soluble substances (COD, BOD, NH4-N), and colloidal and suspended solids do not vary with location in aeration basin. Plug Flow involves relatively long and narrow aeration basins so that concentration of soluble substances and colloidal and suspended solids

Factors Affecting Road / Highway Classification

To identify the classification to which any road belongs, the following factors should be considered: SERVICE FUNCTION:- Most roads provide service to traffic, access to land or both. Following road type provide the service function given as; Freeways and Arterials ==> provide the movement of through traffic. Local roads ==> are used almost exclusively for land

5 Major Classes of Roads - Trunk, Primary, District, Local, Residential

Their main function is to facilitate regional distribution of traffic (intercity movement). They may be national or provincial roads and the type of facilities found in this class are freeways, expressways, dual carriageways and single carriageway main roads. This class of road forms the primary network for the urban area as a whole. All long distance traffic movements to

Types of Settling in Waste Water Treatment Plants

Discrete, non-flocculent particles in a dilute suspension - settle as separate units, and there is no apparent flocculation or interaction between the particles - settling of sand particles in grit chambers. Settling of flocculent particles in a dilute suspension - flocculate during settling and increase in size and settle at a faster velocity - settling in primary

Types of Air Masses and Fronts

If the surface is warm and moist, air in the region becomes warm and moist also. If the air then moves to different regions it takes these properties along, gradually changing in response to the new area. Air masses are designated as cold or warm and moist or dry. It is a boundary between two air masses. The term has its origins analog to military operations as the

Types of Road Intersections and Highway Crossings

Intersection also commonly known as crossroad is any place where two or more than two roads intersect or meet each other at grade. According to a source there are total 973 intersections in Karachi City. Intersections may be signalized or non-signalized, may or may not have a roundabout. The intersections encompassed by a roundabout are considered as safe

Types of Railway Sleepers - Advantages & Disadvantages

Wooden sleepers are the ideal type of sleeper. Hence they are universally used. The utility of timber sleepers has not diminished due to the passage of time. Advantages of Wooden Sleepers They are cheap and easy to manufacture They are easy to handle without damage They are more suitable for all types of ballast
