The ISE sensors are amperometric sensors for monitoring of Chloride (Free or Total), Chlorine dioxide or hydrogen peroxide. It is ideal for all kinds of water treatment and produces stable readings even at high fluctuations of pH, temperature and flow. Strong surfactants are tolerated. - s::can plug & measure - measuring principle: amperometric (membrane covered) - ideal for all kinds of water treatment - long term stable and lowest maintenance in operation - replacement of membrane only once a year - readings stable even at high fluctuations of pH, temperature and flow - strong surfactants are tolerated - factory precalibrated - mounting and measurement in a flow cell - operation via s::can terminals & s::can software - additionally also measures temperature

Keerkleppen of terugstroombeveiligers dienen jaarlijks op hun goede werking en functionaliteit gekeurd te worden. Dit wordt beschreven in het werkblad 1.4G van de Vewin. De complete controle wordt volgens de voorgeschreven meetmethode uitgevoerd (overdruk- onderdruk of de traditionele). U ontvangt een rapport en certificaat ter bevestiging wanneer en met welke methode deze is uitgevoerd. Tevens worden defecte keerkleppen, indien mogelijk in overleg, direct vervangen. Bij een contract wordt u jaarlijks geïnformeerd wanneer de controle weer zal plaatsvinden.

KemConnect DEX is based on performic acid which is a powerful peroxygen compound that disinfects rapidly, and at low doses. Because it is chlorine-free and does not produce toxic by-products, KemConnect DEX is a sustainable disinfection strategy. The efficiency of performic acid (PFA) as a disinfectant enables a cost-effective approach to the disinfection process. The footprint for chemical storage is small, as are the logistic requirements for chemical supplies. The on-site production system that produces performic acid is compact and has low energy requirements. As an added value, Kemira’s expertise and experience in water management expands your in-house capabilities to quickly resolve water treatment challenges. Convenience is a word rarely used when disinfecting wastewater, but with KemConnect DEX it’s a reality. The package includes all the required chemicals, a compact DEX-3 unit with a reactor capable of on-site PFA production and the KemConnect smart process managment system. This turn-key system is fully automated and installed by Kemira. KemConnect DEX is monitored and controlled on a digital platform that automates dosing and has real-time access via the internet on any connected device. System status, alarms and reporting occur via SMS and email. KemConnect DEX has low capital investment requirements, low operating-costs and is an environmentally sound disinfection solution.

Kemira KemConnect P-optimizer helps plant operators to dose the exact amount of coagulants they require for chemical phosphate removal. Continuous monitoring combined with precise control over product dosing allows operators to react proactively to fluctuations in the feed to their wastewater plant. With Kemira KemConnect P-optimizer, overdosing “to be on the safe side” is as much a thing of the past as limit violations that result from the late detection of phosphate peaks. To ensure a quick start-up phase, Kemira installs and calibrates the relevant sensors, supplies the required chemicals, and ensures that your staff receives proper training. We can also manage future maintenance and calibration activities so that you can focus on managing and optimizing your operations. For even smarter chemical management, KemConnect P-optimizer can be combined with KemConnect VMI, our real-time stock-monitoring solution.

Kemira KemConnect™ PT is an automated solution to optimize the chemical pre-treatment process, enabling various downstream efficiency improvements. The system is designed to maximize the energy savings and energy production of a wastewater treatment plant and to maintain a consistent level of treatment within a minimum and maximum range. The application of such a system can limit or prolong the need for major plant expansion while addressing sustainability goals at the same time. The main objective is to settle just enough primary solids to alleviate most of the burden on the aeration process, hence lowering the energy required for aeration. The second objective is to increase biogas production by increasing the amount of more easily biodegradable sludge sent from the primary treatment step to the digestors as opposed to secondary sludge, which is much harder for the bacteria to digest. The system includes the measurement of flow, turbidity, and suspended solids in the influent wastewater, as well as the measurement of ammonium, phosphate, COD, and nitrate and oxidation reduction potential in the nitrification/denitrification process. Feedback input loops from aeration energy and biogas production are also included. Utilizing intelligent algorithms, the optimal chemical dosage for the desired outcome is calculated based on the existing conditions. The service includes the selection and supply of chemistry, provision of online equipment, recommendations for optimal dosage points, and a customized reporting system. The KemConnect platform allows you to continuously monitor all relevant performance parameters and cost savings in real time.

The KemConnect SD service optimizes your chemical sludge treatment prior to the dewatering equipment even under changing process conditions. We apply online analytics and utilize an advanced dosage control algorithm to constinuously optimize your chemical sludge conditioning. The service includes the selection and supply of chemistry, the provision of online equipment, recommendations for optimal dosage points, and a customized reporting system. Kemira’s KemConnect platform enables the continuous monitoring of all relevant performance parameters in real time. Dedicated KemConnect SD dashboards provide our service team with valuable information for application optimization and remote performance control, while you can accurately monitor cost savings to help maintain the efficiency of your sludge dewatering process.

Valbeveiliging en persoonlijke beschermingsmiddelen (PBM's) moeten elk jaar gekeurd worden. Dit is wettelijk verplicht. Tijdens deze keuring beoordelen wij of het middel nog veilig kan worden gebruikt en of het voldoet aan alle normen. Dit kan bijvoorbeeld gaan om helmen, harnassen en ladders. Maar ook permanente valbeveiliging. Door regelmatig te keuren blijven deze middelen betrouwbaar, onmisbaar voor veilig gebruik.

AVK lug/wafer knife gate valves are bi-directional with full and plane bore. The protected sealings and high quality materials bring about a great performance and a long service life. AVK knife gate valves are available with lever, non-rising stem and handwheel, rising stem and handwheel, pneumatic actuator, ISO top flange for actuator or complete with electric actuator. FEATURES - Replaceable top packing gland enables sealing replacement without disassembly of the valve - The valve is self cleaning as particles will be pushed off the gate when opening the valve. For extra protection of the packing gland a scraper is available as an optional extra. - Bi-directional, can be installed independent of the flow direction - Full bore with no reduction of the flow - Plane bottom prevents sediment from being accumulated - No cavity in the body and thus no risk of clogging - U-shaped one-piece NBR sealing between the body parts makes up for tolerances in coating and casting. It is reinforced with a steel insert to protect it from being damaged during operation. - Encaged stem with yokes prepared for mounting of micro switches and inductive censors - Stem and gate connection is secured with self-locking nuts - Supports integrated in the body casting protect the gate from deflecting under pressure - Body of ductile iron with 100-150 μm UV resistant polyester coating, RAL 5017.
