ʻO nā mea ʻike pH maikaʻi wai

ʻO ka waiwai pH o ka wai he hōʻailona koʻikoʻi e ana i ka ʻakika a i ʻole ka alkalinity o ke kino wai, a ʻo ia kekahi o nā mea koʻikoʻi a koʻikoʻi i ka nānā ʻana i ka maikaʻi o ka wai. Mai ka palekana wai inu a hiki i nā kaʻina hana ʻenehana a me ka mālama ʻana i ke kaiapuni, pono ka nānā pono ʻana i ka pH. ʻO ka mea ʻike pH maikaʻi wai ka mea nui no ka hoʻokō ʻana i kēia ana.

I. Nā hiʻohiʻona o ka wai pH Sensors

Hoʻoholo nā mea ʻike pH maikaʻi wai i ka ʻakika a i ʻole ka alkalinity o kahi hoʻonā wai ma ke ana ʻana i ka neʻe ʻana o nā ion hydrogen (H⁺). ʻO kā lākou mau mea koʻikoʻi he aniani membrane electrode pili i nā hydrogen ions a me kahi electrode kuhikuhi. Hōʻike maʻamau nā mea ʻike pH hou i kēia mau hiʻohiʻona:

1. Kiekie a me ka pololei

• Hiʻona: Hiki i nā mea ʻike pH kiʻekiʻe ke hāʻawi i ka pololei o ke ana ʻana o ± 0.1 pH a ʻoi aku ka maikaʻi, e hōʻoia ana i ka hilinaʻi ʻikepili.
• Pōmaikaʻi: Hāʻawi i ke kumu ʻikepili pololei no ka mālama ʻana i ke kaʻina hana a me ka nānā ʻana i ke kaiapuni, e pale ana i nā poho o ka hana ʻana a i ʻole ke kuhi hewa ʻana i ka maikaʻi o ka wai ma muli o nā hewa ana.

2. Pane wikiwiki

• Hiʻona: Hoʻololi koke ka mea ʻike i ka hoʻololi ʻana i ka waiwai pH, maʻamau a hiki i 95% o ka heluhelu hope ʻana i loko o kekona a i ʻumi kekona.
• Pōmaikaʻi: Hiki i ka hopu manawa maoli i nā loli wikiwiki i ka maikaʻi o ka wai, e hoʻokō i nā koi manawa maoli o ka mana kaʻina hana a hoʻomaʻamaʻa i nā hoʻoponopono kūpono.

3. Paʻa maikaʻi

• Hiʻona: Hiki i nā mea ʻike i hoʻolālā maikaʻi ke mālama i nā heluhelu paʻa i nā wā lōʻihi ma lalo o nā kūlana hana paʻa me ka liʻiliʻi o ka neʻe ʻana.
• Pōmaikaʻi: Hoʻemi i ka pono no ka calibration pinepine, hoʻohaʻahaʻa i ka hana mālama, a hōʻoia i ka hoʻomau ʻana o ka ʻikepili a me ka hoʻohālikelike.

4. Nā ʻano like ʻole o ke kau ʻana a me ka hoʻohana ʻana

• Hiʻona: No ka hoʻololi ʻana i nā hiʻohiʻona like ʻole, hele mai nā mea ʻike pH i nā ʻano like ʻole:
  • Papa Hana Hana: Nā hiʻohiʻona paʻa, peni-type, a me benchtop no ka hoʻāʻo wikiwiki ʻana a i ʻole ka hoʻāʻo ʻana i ke keʻena hoʻokolohua pololei.
  • Ke Kaʻina Hana Online Type: Submersible, kahe-ma, nā ʻano hoʻokomo no ka nānā mau ʻana ma ka pūnaewele i loko o nā paipu, nā pahu, a i ʻole nā ​​muliwai.
• Pōmaikaʻi: ʻOi aku ka maʻalahi o ka hoʻohana ʻana, e uhi ana i nā hiʻohiʻona āpau e pono ai ke ana pH.

5. Pono i ka mālama mau a me ka calibration

• Hiʻona: ʻO kēia ka "pōʻino" nui o nā sensor pH. ʻO ka membrane aniani e maʻalahi i ka fouling a me ka pōʻino, a pau ka electrolyte i ka electrode kuhikuhi. Pono ka calibration maʻamau me nā hoʻonā buffer maʻamau (ʻelua-point calibration) a me ka hoʻomaʻemaʻe electrode.
• 'Ōlelo Aʻo: ʻO ka pinepine o ka mālama ʻana e pili ana i nā kūlana maikaʻi o ka wai (e laʻa, ka wai ʻino, ka wai momona kiʻekiʻe e hoʻolalelale i ka ʻino).

6. Naʻauao a me ka hoʻohui

• Hiʻona: Hoʻohui pinepine nā mea ʻike pH pūnaewele hou i nā mea ʻike wela (no ka uku wela) a kākoʻo i nā huahana kikohoʻe (e laʻa, RS485, Modbus), e ʻae i ka pilina maʻalahi i nā PLC, nā ʻōnaehana SCADA, a i ʻole nā ​​​​pae kapua no ka nānā mamao a me ka nānā ʻana i ka ʻikepili.
• Pōmaikaʻi: Hoʻomaʻamaʻa i ke kūkulu ʻana i nā ʻōnaehana nānā automated, hiki i ka hana mālama ʻole ʻia a me nā hana hoʻāla.

II. Nā Kūlana Hoʻohana Nui

ʻO ka hoʻohana ʻana i nā mea ʻike pH he ākea loa, e uhi ana i nā wahi āpau e pili ana i ka wai.

1. ʻO ka mālama ʻana i ka wai ʻino a me ka nānā ʻana i ka mālama ʻana i ke kaiapuni

• Nā mea kanu hoʻomaʻemaʻe wai kaona/ʻoihana:
  • Nā Manaʻo Hoʻohana: Inlet, outlet, biological reaction tanks (aeration tanks), hoʻokuʻu ʻia.
  • Role: Hāʻawi ka nānā ʻana i ka pH inlet i ka ʻōlelo aʻo mua o nā haʻalulu wai ʻino; pono ke kaʻina hana lāʻau olaola i kahi pae pH kūpono (maʻamau 6.5-8.5) e hōʻoia i ka hana microbial; Pono ka pH effluent e hoʻokō i nā kūlana ma mua o ka hoʻokuʻu ʻana.
• Ka nānā ʻana i ka wai ambient:
  • Nā Manaʻo: Nā muliwai, nā loko, nā moana.
  • Mahele: E nānā i nā kino wai no ka haumia mai ka ua waikawa, ka wai ʻino ʻoihana, a i ʻole ka hoʻoheheʻe wai mai kaʻu wai, a nānā i ke olakino kaiaola.

2. Ka Mana Hana Hana Hana

• ʻOihana Kimia, Laʻau Laʻau, Meaʻai & Mea inu:
  • Nā Manaʻo Hoʻohana: Reactors, hui ʻana i nā pahu, pipelines, nā kaʻina hoʻohui huahana.
  • Role: ʻO ka pH kahi ʻāpana koʻikoʻi no nā hopena kemika he nui, e pili pono ana i ka nui o ka hopena, ka maʻemaʻe o ka huahana, ka hua, a me ka palekana. No ka laʻana, i ka hana waiu, pia, a me ka mea inu, ʻo ka pH ke kī i ka mālama ʻana i ka ʻono a me ke ola o ka papa.
• ʻO ka paila a me nā ʻōnaehana wai hoʻoluʻu:
  • Nā Manaʻo Hoʻohana: Wai hānai, wai paila, wai hoʻoluʻu hou.
  • Role: E hoʻomalu i ka pH i loko o kahi kikoʻī (ʻo ka alkaline maʻamau) e pale ai i ka corrosion a me ka scaling o nā paipu metala a me nā mea hana, hoʻonui i ke ola lawelawe a hoʻomaikaʻi i ka hana wela.

3. Ka Mahiai a me ka I'a

• Aquaculture:
  • Nā Manaʻo Noi: Nā loko iʻa, nā pahu ʻōpae, Recirculating Aquaculture Systems (RAS).
  • Role: Pili loa ka iʻa a me ka ʻōpae i nā loli pH. Hoʻopilikia ka pH kiʻekiʻe a haʻahaʻa paha i ko lākou hanu, metabolism, a me ka pale ʻana, a hiki ke make. Pono ka nānā mau ʻana a me ke kūpaʻa.
• ʻO ka wai mahiʻai:
  • Nā Manaʻo Noi: Nā kumu wai wai, nā ʻōnaehana fertigation.
  • Hana: Hiki i ka wai ʻakika nui a i ʻole ka wai alkaline ke hoʻopilikia i ke ʻano o ka lepo a me ka maikaʻi o ka mea kanu, a hiki ke hōʻino i nā aʻa hua. ʻO ka nānā ʻana i ka pH e kōkua i ka hoʻonui ʻana i ka nui o ka wai a me nā mea momona.

4. Ka wai inu a me ka wai kaona

• Nā Manaʻo Noi: Nā kumu wai no nā mea kanu lapaʻau, nā kaʻina hana lapaʻau (e laʻa, coagulation-sedimentation), wai i hoʻopau ʻia, nā pūnaewele paipu aupuni.
• Role: E hōʻoia i ka pH wai inu i nā kūlana aupuni (e laʻa, 6.5-8.5), ʻono ka ʻono, a mālama i ka pH e hōʻemi i ka ʻino i loko o ka pūnaewele hoʻolako, pale i ka "wai ʻulaʻula" a i ʻole "wai melemele".

5. ʻImi ʻepekema a me nā Laboratories

• Nā Manaʻo Noi: Nā Laboratories ma nā kulanui, nā keʻena noiʻi, nā kikowaena R&D hui, a me nā keʻena hoʻāʻo kaiapuni.
• Mahele: E alakaʻi i ka nānā ʻana i ka wai, nā hoʻokolohua kemika, nā moʻomeheu olaola, a me nā noiʻi ʻepekema āpau e koi ana i ka ʻike pololei o ka ʻakika a i ʻole ka alkalinity.

Hōʻuluʻulu manaʻo

ʻO ka wai pH sensor kahi mea hana ʻenehana ʻoi loa akā pono ʻole. ʻO kona mau hiʻohiʻona o ke kiʻekiʻe kiʻekiʻe a me ka pane wikiwiki e lilo ia i "sentry" o ka hoʻokele wai maikaʻi. ʻOiai pono ia i ka mālama mau, ʻaʻole hiki ke hoʻololi ʻia kāna waiwai noi. Mai ka nānā ʻana i ka muliwai e pale ana i ke kaiapuni a hiki i ka mālama wai inu e hōʻoiaʻiʻo ana i ka palekana, mai nā kaʻina hana ʻoihana e hoʻomaikaʻi ana i ka pono a hiki i ka hoʻonui ʻana i ka hoʻonui ʻana i ka hoʻonui ʻana i ka mahiʻai hou, ʻo ka pH sensor ka mea koʻikoʻi ma ke ʻano he mea koʻikoʻi i ka mālama ʻana i ka maikaʻi o ka wai a me ka hoʻomaikaʻi ʻana i nā kūlana hana.

Hiki iā mākou ke hāʻawi i nā ʻano hoʻonā like ʻole no

1. ʻO ka mika paʻa lima no ka maikaʻi o ka wai

2. Pūnaehana Buoy lana no ka maika'i o ka wai

3. Palaki hoʻomaʻemaʻe ʻakomi no ka ʻike wai ʻokoʻa

4. Hoʻopiha piha i nā kikowaena a me nā polokalamu uila uila, kākoʻo iā RS485 GPRS / 4g / WIFI / LORA / LORAWAN

No nā mea ʻike wai hou aku ʻike,
