Valmet Total Solids Measurement - Valmet TS
Valmet Total Solids Measurement (Valmet TS), based on microwave technology, is a reliable and accurate meter for all wastewater sludge treatment applications (0 – 40% total solids), providing savings in energy, polymer dosing, and transportation.
Features
Digester feed: Maintaining a high, optimized total solids content in the sludge entering the digesters helps to achieve better process control and significant savings. This will also decrease electricity costs, and a higher intake digester capacity means that new investments can be postponed.
Dewatering: Valmet Total Solids Measurement (Valmet TS) helps in optimizing polymer dosages and thus reducing polymer costs. The quality of both the dewatered sludge and centrate water is stabilized. Better dewatering efficiency in turn reduces sludge transport costs and improves incineration efficiency if the sludge is eventually burned. Dewatering equipment can be run for shorter times, which lessens energy consumption and maintenance costs.
Benefits
- Maintenance free measurement
- Fewer laboratory analyses
- Single point calibration
- Long experience and know-how in microwave technology

Customer success stories
New measurement method of Sludge Total Solids Content at Stockholm Vatten och Avfall
When Henriksdal's sewage works had to change to a new sludge total solids content meter, they chose Valmet TS from Endress+Hauser. This is a microwave-based inline meter in the form of a pipe section that is installed in series with the pump.
Valmet Sludge Dewatering Optimizer improves dewatering at Norske Skog
Norske Skog in Bruck an der Mur, Austria decided to purchase a Valmet Sludge Dewatering Optimizer (Valmet SDO) solution to stabilize the process and improve boiler operation. Integrated to the existing Valmet DNA distributed control system, the software package was accompanied by a Valmet Total Solids Measurement (Valmet TS) microwave transmitter to measure the total solids amount to sludge dewatering.
Finding the sweet spot for the polymer dose
In order to improve effectiveness, the Mitchells Plain Wastewater Treatment Works operated by the City of Cape Town, South Africa, installed two Valmet Total Solids Measurements (Valmet TS) in the sludge cake pipelines to provide immediate inline feedback on the dry solids percentage of the sludge cake.
Online total solids measurement is a winner
Energy savings and lower polymer costs in sludge treatment are among the benefits gained with Valmet Total Solids Measurement (Valmet TS) at Kajaanin Vesi in Finland. In 2012–2013, the plant modernized its sludge treatment facility and had four Valmet TS units installed in the process. This reliable total solids measurement solution, based on microwave technology, is suitable for all wastewater sludge treatment applications in the range of 0–40% total solids.
Valmet goes underground to help treat wastewater
The Kakolanmäki waste water treatment plant, jointly owned by 14 municipalities, has been operating in the southern Finnish city of Turku since the beginning of 2009. Since the plant is built underground it has a more constant and higher temperature than surface facilities, a distinct advantage for treatment conditions. It is able to process the wastewater from 300,000 people and various industrial sources in a way that considerably reduces the nutrient load on the Baltic Sea.
ProRheno optimizes processes with Valmet TS
The Valmet TS device makes the reliable and accurate measurement of solids content in sewage sludge of different origin possible - and this at minimal maintenance efforts.
Valmet wastewater solutions save energy and chemicals
Tampere Water recently installed several Valmet total solids measurement devices and a sludge dewatering control package at its Viinikanlahti wastewater treatment plant in Tampere, Finland.
Optimum water content derives benefits
One of the largest sludge plants in Kanto area Japan, 400,000 ton/day. Valmet TS measures water content of dry cake and it is used for feed-back control of polymer amount to belt-press dewatering machine.
On-line measurement with laboratory accuracy
The Anjalankoski Mill area is home to two of Stora Enso's production units, the Anjala Paper Mill, as well as the Inkeroinen Board Mill. Cooperative efforts between the mills cover raw materials, energy and power generation, as well as waste water treatment and resultant sludge drying and firing.
Accurate sludge solids measurement means big savings
A USA waste treatment plant sees a $1.2 million/yr reduction in chemical and energy costs with the implementation of Valmet TS online measurements and automatic centrifuge controls.
A Canadian city: Valmet TS troubleshooting leads to polymer and maintenance savings
A Canadian city with a population of about 95,000 operates an 80 million liter/day capacity wastewater treatment plant which discharges clean and UV sterilized water to the local river.
Valmet's transmitter serving 2.4 million people
In the Beijing Gaobeidian Wastewater Treatment Plant, sludge total solids from the primary clarifier varied from below 1 to 60 g/l, which means that from time to time only water is pumped to the sludge thickening tank. The Valmet TS total solids transmitter was installed in the outlet of the primary clarifier to control pumping.
Valmet Total Solids measurements to a large-scale sludge treatment plant in Hong Kong
Valmet has delivered six Valmet Total Solids measurements to a state-of-the-art sludge treatment plant in Hong Kong. At the moment the plant is being commissioned, with two of the four incinerators already started.
