Coagulation and Flocculation by controlled Turbulence The PFR pipe Flocculator is a plug flow reactor in which process such as coagulation, flocculation, demulsification, precipitation and pH control can take place under highly controlled and well defined conditions. The above mentioned processes take place under turbulent flow conditions. At the chemical injection points the pipe diameter is adapted to ensure instantaneous mixing of chemicals and wastewater. Through the crosssection of a pipe the mixing intensity is virtually homogeneous. Reaction time is determined by the pipe length and flow rate and based on the exact requirements, no excess is required . In the plug flow reactor the process can be influenced at any time as opposed to tank reactors, where only condition per tank can be maintained. Generally speaking a pipe flocculator is used where a coagulant, a flatulent and optionally a chemical for pH correction are dosed in sequence for the remove all of turbidity and / or COD or precipitants. The use of a pipe flocculator in combination with a flotation system can give COD removals of up to 95%. K-pack Systems has a wide experience in chemical treatment, particularly in the use and selection of coagulants and flocculantsin combination with a PFR pipe flocculator. The PFR pipe flocculator is exceptionally suitable for our latest developments in the non-toxic biodegradable coagulants and flocculants range.

JAR TEST The choice and dosage of the chemical coagulant to be adopted for removing suspended solids from waste-water are established based on an evaluation of the results obtained from the Jar Test. Multiple stirrers with reproducible stirring speeds ensure repeatable and reliable results. LEACHING TEST This is a test on solid wastes to be sent to the dump that uses diluted acetic acid or carbon dioxide-saturated water to detect the presence of toxic heavy metals. JLT 4 AND JLT 6 – JAR & LEACHING TESTS The JLT 4 and JLT 6 are multiple stirrers with reproducible stirring speeds allowing standard conditions to be met during analysis, a basic requirement in order to obtain reliable and repeatable results. The highly versatile stainless steel stirring shafts offer height adjustment and are fitted with a self-locking device with clutch. The sample can be backlit for easier reading. The instrument has an ergonomic design and the control panel is sloped to facilitate parameter settings and readings. The rotation speed can be set from 10 to 300 rpm, with 1 rpm intervals, the time remaining can be set in hours or minutes. FP4 – PORTABLE FLOCCULATOR The FP4 is the portable Flocculator that can be connected to a battery or a car cigarette lighter socket. The anti-skid base ensures stability whilst the highly versatile stainless steel stirring shafts offer height adjustment and are fitted with a self-locking device with clutch. The FP4 is particularly suitable for carrying out on-site Jar Tests. FC4S / FC6S - FLOCCULATORS The FC4S and FC6S are highly resistant to chemical and mechanical aggression and corrosion. The highly versatile stainless steel stirring shafts offer height adjustment and are fitted with a self-locking device with clutch. The sample can be backlit for easier reading. Motion is transmitted by four (in the case of the FC4S) or six (in the case of the FC6S) direct current gear motors in order to ensure optimum performance and reproducibility even at low speeds. With 9 different speed settings for each position the instrument is totally flexible; the stirring speed can be set using the selectors on the front panel (10-15-30-45-60-90-120-150-200 rpm). On demand version can reach 300 rpm.
