“Major Advantages of PVC Sheet Piles
Vinyl sheet piles are made of poly vinyl chloride also known as PVC: a material with excellent resistance to weather influences and it has a long service life. Moreover, the material will not be affected by natural forces occurring in the ground, rodents, and salt or fresh water. PVC sheet piling has a number of benefits over traditional steel timber or concrete piling, including, costs, durability, ease of handling and a reduced environmental impact.

There are a large number of techniques to drive vinyl sheet piles. The system used largely depends on the circumstances. In some situations, particularly when short lengths of Plastic Piling are being installed, it can be inserted into the ground manually by using a maul and pile cap. This is often the case in peat land areas, where the ground conditions are more favorable. When installing longer lengths, or where the ground conditions are more difficult, a piling hammer should be used. Driving the sheet pile directly can be done with a standard pneumatic hammer or a light vibrator with or without a clamp. This system is only suitable for driving at light conditions and to a limited depth.

For heavy conditions and installation from 4m up to 8m depth, it is advisable to use a steel support sheet pile with exactly the same shape as the PVC profile. With support harder soil can be penetrated and installation is speeded up because the hammer does not have to be disconnected from the steel guiding sheet pile. Now let’s have a look at its advantages and disadvantages:

ADVANTAGES

Does not rot or rust.

Manufactured from recycled plastic.

Resistant to the majority of chemicals.

Not affected by salt water.

Light weight, easy handling.

Reduced impact on natural resources.

DISADVANTAGES

Limited free standing height.

Not reusable.

We should know that industrial sludge contains a lot of heavy metals, which, if not handled properly, can have a huge impact on the environment or human health. Before the popularization of sludge dryer, a lot of people will bury the industrial sludge, you should know that the industrial sludge moisture content is high, the smell is big, some chemical components in the sludge will kill the bacteria in the soil, thereby damaging the original structure of the soil, make the soil lose vitality; At the same time, the sewage in the industrial sludge will permeate into the underground, causing pollution to the groundwater. If the industrial sludge is placed in the open air, the harmful gases in the sludge will be released, not only causing pollution to the atmosphere, but also causing harm to the human body. Therefore, how to treat these industrial sludge is very important. The sludge dryer adopts the box structure as a whole, and the internal air is all closed cycle. The dehumidification capacity of the unit is absolutely not affected by the external environment temperature. There is no gas leakage and no gas pollution. In the drying process, the sludge can dehydrate quickly, and the moisture content of the dried sludge is especially low, showing a loose and loose state, which is convenient for transportation and treatment. Here are some features of sludge dryer:

Sludge dryer has compact structure, small floor space, less auxiliary equipment, saving investment and operating cost.

The sludge dryer adopts the way of conduction heating, the heat transfer area is large, the heat loss is small, the heat utilization rate can reach more than 90%.

The wedge-shaped paddle of the sludge dryer has the self-cleaning ability and can maintain the efficient heat transfer function.

Sludge drying degree and particle size are uniform after drying by sludge dryer.

sludge dryer drying process adjustable high, easy to operate and control.

The sludge dried by the sludge dryer contains high calorific value and organic components, which is a renewable resource with utilization value and meets the requirements of environmental protection.

10 Reasons to Use Fine Bubble Diffusers in Wastewater Treatment
Fine bubble diffusers are needle-shaped perforated panels. There are also other fine bubbles of various sizes including standard disc and other tubes which have at least 1 mm perforations. Fine bubbles with larger apertures are referred to as medium bubbles, and their size is at least 2 mm. The way standard fine bubbles perform is well understood in the market. The most understood facts are that the fine bubbles do their work by providing 2%/ft – 6.5% /ft standard oxygen transfer efficiency, otherwise referred to as SOTE. When they are new, they drop the pressure by 12” WG – 30 mbar. They usually produce bubbles ranging from the sizes of 1 mm to 3 mm. When you compare fine bubble differs with coarse bubble diffusers, the differences are glaring. First of all, coarse bubble diffusers fail to meet the challenges that fine bubble diffusers can withstand. They usually last for one or two years before they crack, blow off or clog. So, what are the advantages of using fine bubble diffusers in wastewater treatment?

High Aeration Efficiency

Aeration Tanks have Improved Levels of Dissolved Oxygen

Fine Bubble Aeration Tanks are Easy to Maintain

The Entire Water Column Gets Circulation

Fine Bubble Diffusers Have Long Operational Life

There are many advantages of using fine bubble diffusers in wastewater treatment. The devices have been in the market for over 20 years. The machines have proved their efficiency over time as well as their ability to perform exceptionally well underwater. If you select the right machine, you will have a device that will operate with efficiency at low operational and maintenance costs.

WHAT IS THE PURPOSE OF MBBR MEDIA?
A bed of MBBR media generally consists of thousands of tiny pieces that suspend themselves throughout a wastewater treatment tank, typically taking up about 50% to 70% of the available space. Their design makes them optimal for hosting beneficial bacteria and promoting their growth. Many types of MBBR media resemble wheel-shaped pasta, with the spokes of the wheel providing valuable surface area for bacterial growth. Others are thin, coin-shaped discs or squares. MBBR media carriers are ideal for use in aeration tanks. They disperse throughout the tank, and their bacteria help decompose the solid waste. The media are so effective because their design gives them a tremendous amount of surface area for beneficial microorganisms to settle on, so they help increase the number of bacteria available to digest waste. How do the MBBR media carriers work? In an aeration tank, the tiny MBBR pieces disperse throughout the wastewater, and their tremendous surface area provides a hospitable environment for microorganism growth. The biofilm that grows on the media then decomposes the waste in the tank. Diffusers send oxygen into the tank to promote continuous microorganism growth, and a mesh sieve in the tank helps keep the media carriers from flowing away with the wastewater. MBBR media carriers have a density similar to that of water, so they mix well with the wastewater to promote consistent waste digestion. Using MBBR media is particularly advantageous because the tiny pieces take up minimal space, are easy to maintain and digest waste efficiently. The microorganisms on the media can also automatically adjust to changes in the amount and type of waste in the water. Although MBBR systems require some monitoring, they are largely self-sufficient.
