Travels with Paul – Quarries and Wastewater Treatment Works

We followed Paul’s visits in February so we could show you just what a Partech sales engineer does! The month started off in Romsey where Paul carried out a site survey at a very muddy quarry… Paul went to see if Partech could help with their flocculent dosing control. The Partech team are pretty certain they’ll be able to offer an excellent solution, but Paul went to lend a ...

Enhancement of microbubble generation in a pressurized dissolution process by packing the nozzle with porous ceramics

The pressurized dissolution method is often used for microbubble generation. However, the main disadvantage of this method is that a large amount of energy (more than 0.3 MPa) is required to generate many microbubbles, each of which have a diameter of several dozen μm. To overcome this problem, we investigated the effectiveness of porous ceramic when used as the packing material in the ...

Treating Plating Wastewater

Plating wastewater contains heavy metals, oil and grease and suspended solids at levels that might be considered hazardous to the environment and could pose risks to public health. Heavy metals, in particular, are of great concern due to their toxicity. Because of the high toxicity and corrosiveness of plating waste streams, plating facilities are required to pretreat wastewater prior to ...

Full-Scale Experience with the Sharon Process through the Eyes of the Operators

ABSTRACTThis paper summarizes different operating aspects and experiences of several SHARON plants. The SHARON process is suitable for treatment of high strength ammonia wastewaters such as reject water from dewatering of digested sewage sludge and wastewater from sludge drying or incineration plants. The aerated retention time and nitrite concentration are the two most important process ...

New developments in filter cartridges for reverse osmosis pre-filtration

Reverse osmosis (RO) pretreatment systems are designed to reduce suspended solids to a level that will provide the most suitable conditions for the performance of the membrane system. Depending upon the quality of the feed water, pretreatment may include settlement, clarification, multi-media filtration, and chemical treatment. However, sediment pre-filtration is always required to ensure that ...

How & Why We Measure Suspended Solids

In case you weren’t sure, Suspended Solids is simply a density measurement used to describe exactly how much waste sludge and particles are in the water, and is measured in milligrams per litre (mg/l), grams per litre (g/l) or percentage solid (%). 1000mg/l = 1g/l = 0.1%. It is used to calculate the amount of material, or load, in a wastewater or industrial system. Suspended Solids can be ...

Spatial and seasonal distribution of phosphorus in the mainstem within the Three Gorges Reservoir before and after impoundment

The Three Gorges Reservoir (TGR) began to store water in 2003. The water level reached 135 m in 2003, 156 m in 2006, 172 m in 2008 and 175 m (target level) in every year from 2010 through 2013. Impacts of dams on the environment are a concern all over the world. A major concern for reservoirs is phosphorus and possible eutrophication. Therefore, total phosphorus (TP) in the TGR mainstem was ...

Membrane Bioreactors for RO Pretreatment

ABSTRACTCurrently, treated municipal wastewater is typically discharged to the environment in most parts of the world. It is, however, a potential water resource from which high quality water for reuse can be produced. Reuse applications include both non-potable applications such as irrigation and production of industrial process water, and indirect potable reuse including aquifer recharge. For ...
